Eaze is just one of several firms taking advantage of the legalisation of cannabis, for which the people of California voted overwhelmingly in favour in 2016.

Since January last year, when the use of recreational cannabis became legal across the state, the start-up has seen an 80% increase in sign-ups.

It had run a limited medicinal cannabis delivery service since 2014, with anyone who wanted to order having to download medical evidence that they needed it.

But now the mood has changed and 10 states around the US have made recreational cannabis legal, with the use of the drug for medical reasons allowed in 33 of the 50 states.

"People used to consume with their friends and would have had a guy that delivered. Now a lot of people feel more comfortable about coming out of the shadows about their cannabis consumption," said Sheena Shiravi, director of communications at Eaze.

Not everyone is convinced about the new laws though, with doctors in the US and Canada - where it was also recently legalised - urging caution when it comes to usage, both in terms of addiction and the effects of the drug on the brain, particularly for young people.

Dr Romina Mizrahi, a doctor at Canada's Centre for Addiction and Mental Health, has done a lot of research into the link between cannabis use and psychosis. She believes it can be dangerous to smoke the drug under the age of 25.

"When people start smoking before the age of 16, there is a higher risk of having a psychotic experience. We know that early use is dangerous," she told the BBC.
Opiate crisis

According to Ms Shiravi, the vast majority of her company's users (80%) cite their use of the drug as being for general "wellness".

"It helps with stress levels, decreases alcohol consumption and cannabis is a lot safer than alcohol," she told the BBC.

For her, use of marijuana can also help alleviate the US's opiate crisis, which has seen addiction to shop-bought painkillers skyrocket.

"Cannabis is a huge tool missing in the toolbox of pain management. It is not a silver bullet but should definitely be considered in the face of hundreds of thousands of opioid deaths," she said.
